Which expression shows how the distribuive property can be used to multiply 8x29?
Natasha_Volkova [10]

The expression which shows how the distributive property of the can be used to multiply 8×29 as in the task content is; 8(20 + 9).

<h3>Which expression can be used to show how the distributive property can help multiply 8×29?</h3>

It follows from the task content that the given product to be multiplied is; 8×29.

Consequently, it follows from convention that the distributive property of multiplication allows that the multiplication in this case can be rewritten as follows;

8×29 = 8 (20 + 9)

Hence, we have; (8×20) + (8×9).

How to solve this problem?
valentinak56 [21]

Very nice handwriting but the math and English are confusing.

Let's assume we're told

\displaystyle 45 = \sum_{i=1}^9 (x_i - 10)^2

The subscript is important.

I think we're told the similar sum with 11 gives the smallest possible value for the sum. This is a rather cagey way of telling us 11 is the mean of the nine points. The mean is the number which minimizes the sum of squared deviations.

\displaystyle 45 = \sum_{i=1}^9 (x_i - 10)^2 = \sum x_i^2 - 20 \sum x_i + 9(100)

\displaystyle  \sum x_i^2=  20 \sum x_i  - 900

If 11 is the mean, the sum of the points is 9(11)=99.

\displaystyle  \sum x_i^2=  20 (99)  - 900 = 1080

Answer: 1080

Pecans cost $8.25 for 3 pounds. what is the cost of 5 pounds of pecans?
Dominik [7]
You want to find the cost for one pound of pecans.
Divide 8.25 by 3.
8.25/3= 2.75
So it's $2.75 for one pound of pecans.
You want to find the amount for five pounds, so multiply 2.75 by 5
2.75 x 5= 13.75
It costs $13.75 for five pounds of pecans.
